A google search seems to show people on the internet are generally not enthusiastic about its impact resistance relative to polycarb.
Lexan is much more impact resistant based on one Google search result that I found. That being said, a mentor on another team tested the Duraplex by striking it with a hammer and it did not shatter. It will depend on the application of the design that will lead to a material selection.

Since the OP didn't show a design or list requirements (roller arms could be something internal to the robot), I listed alternative products for consideration.
